apalis/colibri_t30: initialise tps65911 gpios
Initialise TPS65911 GPIOs: - disable internal pull-down resistors to decrease (RTC battery) current consumption - output 0 during sleep state on GPIO2 (EN_VDD_CORE) and GPIO6 (EN_VDD_HDMI) While at it also remove some obsolete includes, update some comments, fix some indenting and FIXED_REG resp. GPIO_REG ids. Signed-off-by: Marcel Ziswiler <marcel.ziswiler@toradex.com> Acked-by: Max Krummenacher <max.krummenacher@toradex.com>
